Answer: Yes
Explanation:
Sperm, the male sex gamete stored in the seminiferous tubule have a LIFE SPAN of about five (5) days.
So, once extracted it remains viable and WILL fertilize any viable egg.
Note that fertilization is possible as long as the sperm remain alive AND the eggs are also viable.
option A - Yes is the answer
The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
Key is to Lock as Substrate is to Enzyme
A substrate is a necessary component for an enzyme to become active. It is a specific shape that fits perfectly into an Active Site on the enzyme.
